IBTJNGH BUILDER.

Application led May 5,

ylfhis invention relates to bunch builders for spinning machines, wherein the yarn is first wound upon the bobbin to forni a primary winding or bunch and thereafter a secondary or main winding of the yarn is laid upon thebobbinv to complete the building of the yarns thereon.

ln the winding of thread and yarn on lilling bobbius it is customary to form a primary 1winding' or bunch which is adapted to come into Contact with a feeler carried on the loom which serves as an indicating means when the yarn has been unwound to a predetermined extent, and tie operator is then enabled at the proper time to remove the unwound bobbin and replace a. full bobbin therefor. It is obvious Athat should the bunch not be placed'in a proper position on the bobbin, the same will be ineffective to properly operate the feeler, thus resulting in imperfect weaving, and the production of defective goods. lt is accordingly the pur pose of our invention to produce a perfect bunch in the same position on all bobbins and with this object in view, we provide a positive gear drive and provide means for effectively retaining the device out of bunching position until after the ring rail has been ino-ved into its lowermost position by the operator as customary when beginning the winding of a fresh bobbin, thereby preventing any imperfection in the main winding by the bunch builder.

Other objects and advantages reside in the specific construction, combination and arrangement of the various elements forming.

the invention as more fully hereinafter de-V scribed and claimed, reference being had to the accompanying drawing, forming a part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1 is a front elevation of a portion of a spinning frame, with our invention shown in operative position thereof.

Figure 2 is an enlarged side elevational view, showing t-he bunch building mecha,- nism.

Figure 3 is a top plan View thereof.

Figure d is a detail showing the bunch builder in inoperative position, and

Figure 5 is a similar view showing' the same in position ready to begin operaton.

Referring now to the drawing, we have shown our invention as adapted for use upon a spinning frame indicated at 5, upon which from ythe main frame,

Serial No. 188,99d.

is arranged the usual spindle reel 6, provided with rotatable spindles for the bobbin 7, adapted to be carried on the ifertically reciprocating spinning Wheel 8.

A lift rod 9 extends downwardly from the ring rail and is adapted to be actuated at its lower end by a pivotally mounted rocker arm 10, having a weight 11 at one end thereof.V An arm` 12 is attached to the arm 10, the arm 12 having' ay cable 13 attached thereto extending over a pulley 1/1 and to which a chain 15 is attached engaging a socket 16, keyed on a stub shaft 1T. The shaft 1? extends laterally from an oscillating bunch building arm 18, pivotally mounted by a pin 19, secured to the main frame. i

A cam is mounted `upon a shaft 21, rotatably supported by the main frame, said shaft being operated by any suitable means, the earn being adapted to engage a ruler 22 arranged on the Yarm 18` The cam 20 contacting with the ruler Q2 operates to oscillate the arm 18 whereby to raise and lower the ring rail during the main winding of the bobbin.

To the arm 18 is lixedly secured a sub-` stantially U-shaped bracket 9.3 by a bolt 24;. Between the arms of the bracket is pivotally mounted the lower ends of a separating arm 2e, upon a shaft 25. The arm 24 is arranged in section including an upper section 25 and a lower section 9,6 as shown in Figure 2 of the drawing and provided with slots 27 at their connected ends thereby to secure thesame in extended position by bolts 28. The upper end of the section 25 is provided with a gear segment 29 which is provided with'alternating sections of short teeth 30 and relatively long teeth 31. The gear segment V29 is arranged to engage a gear wheel 32, concentrically arranged with the cam 20 on the cam shaft 21.'V An angularly constructed trip arm 38 i s provided, having one end rotatably supported between the arms of the U-shaped bracket 23 and the opposite end extending upwardly and over a roller 34:, extending a weight 35 being secured on thel free end of the trip arm. The portion of the arm engaged by' the roller is of a substantially U-shaped formationhinvertedly arranged and adapted to rock back andk forth on the roller as the building arm 18 is oscillated. Figures l and 5 of the drawing show the extent of movement of the armupon the roller, Figure 4 showing the relation of the arm with the gear segment i-n extreme rearward position, whereas Figure 5 f shows the bar in an opposite position.

Mounted on the opposite end of the arm 33 is keyed a trip `86, the tripV being arranged to engage oncedge of the arm 24 carrying the gear segment. To the outer edge of the Y bracket 23 is secured a U-shaped arm restr 37, the sides of the arm rest defining the limitation of the forward and backward movement of the gear segment arm 24.

l It Will be noted that thepsaid trip 36 is arranged to engage the rear edge of the cam segment arm 24.so that When thebuilding arm 18 is moved intoit-s lowermost position to` begin the Winding of the yarn, the trip will operate to move the gear segment forwardly Vas shotvn in Figure 5. Thus,`the first motion imparted to the cam shaft 21 Will cause theV gear segment to move forwardly to the position shown byv Figure 4, this movement `being completed before the main Winding actionjof the cam 20 has started. Because of the variation inthe size of the gear segment, the building arm will be caused to quickly Voscillatel suiiiciently to lproduce the primary or bunch-Winding. As soon as the bunch first full stroke, and the gear segment remains idle inV itsforvvard position Vuntil the main Winding has been `completed and the bobbin changed. y V i Itis'tolbeunderstood that various changes or modifications in the details of construction and arrangement may be made Without departing from the spirit of the invention'or the scope of the appendedclaims.
